Steel Body PDC Bits 8-1/2” S419 Adding Value through Performance

Product Number TBD

Design Features: • Cutters are strategically placed in

3D spatial coordinates for maximum work rate efficiency, minimum cutter wear, and maximum penetration rate

• 4140 alloy steel body is precision CNC machined for maximum blade and body strength

• Super Tough Tungsten Carbide hardfacing in critical areas for increased erosion and abrasion resistance

• Gage pads have Tungsten Carbide inserts and Super Tough hardface for maximum gage protection

• Parabolic profile is optimized for

blade count, cutter quantity, and bit stability for a precise round hole

• Force balanced PDC cutter locations on asymmetric blades reduces drilling harmonics, minimizes whirl, and promotes dynamic bit stability

• Internal carbide fluid path eliminates internal erosion
